Resonant behavior in a finite array that appears as (modulated) impedance or current-amplitude oscillations may limit its bandwidth substantially. Therefore, simulations should predict such behavior. Recently, a new approach has been developed, called the eigencurrent approach, which can predict resonant behavior in finite arrays. Analysis of line arrays of H-plane oriented microstrip rings by the eigencurrent approach reveals that resonant behavior is caused by excitation of one of the
